Total 1729 Escherichia coli isolates were obtained from feces of 138 humans, 376 domesticated animals (chicken, duck, beef cattle, dairy cattle, and swine), and 24 wild geese, including 96 isolates from the Yeongsan River in Jeonam Province, Korea. Genotypically unique strains were indicated using Horizontal fluorophore-enhanced rep-PCR DNA fingerprinting (HFERP) [1]. Multiplex PCR analysis done for phylogenetic grouping [2] indicated that none of the strains belonged to E. coli phylogenetic group B2. In contrast, phylogenetic group B2 strains were detected in about 17% (8 of 48 isolates) from 24 wild geese feces and in 3% (3 of 96) isolates obtained from the Yeongsan River. The distribution of E. coli strain in phylogenetic groups A, B1, and D varied depending on the host examined. Another multiplex PCR analysis was done for virulence gene detection targeting eaeA, hlyA, stx1, stx2, est, elt and ipaH [3, 4]. Subsequently, the distribution of E. coli virotypes of Enteropathogenic E. coli (EPEC), Eenterohemorrhagic E. coli (EHEC), Enteroinvasive E. coli (EIEC) and Enterotoxin producing E. coli (ETEC), were determined. Total 89 unique strains were assigned to the 4 virotypes as follows: EHEC (18 strains), EIEC (41 strains), EPEC (9 strains) and ETEC (14 strains). Virulence genes were most frequently present in the phylog ... 전체 초록 보기
